Docket:P89LPC915/916/9178-bit microcontrollers with accelerated two-clock 80C51 core 2 kB 3 V flash with 8-bit A/D converterRev. 05 -- 15 December 2009 Product data sheet1. General descriptionThe P89LPC915/916/917 are single-chip microcontrollers, available in low-cost packages, based on a high performance processor architecture that executes instructions in two to four clocks, six times the rate of standard 80C51 devices. Many system-level functions have been incorporated into the P89LPC915/916/917 in order to reduce component count, board space, and system cost.
